To all whom it may concern:

Be it known that we, FRANK W. BURPEE andJoHN H. BURPEE, subjects of the King of Great Britain, and residing at the c ty of Bellingham, in the county of Whatcom and State of Washington, have invented certain new and useful Improvements in Receptacle-Forming Machines, of which the following is a specification.

The present invention pertains to an automatic machine of the above type primarily devised for working up receptacle bodies from previously prepared paper blanks, and is directed in particular to the provision of a self-feeding progressive machine capable of bending a sector-shaped blankto conical form, and finally ejecting the formed. article.

Further, the invention resides in the provision of novel mechanism for bending a blank to form by successive operations commencing on a midway section of the blank. Another object consists in novel provision for feeding the blanks.

Further objects will be set forth as the description progresses'and those features of construction, arrangements and combinations of parts on which we desire protection, succinctly defined in our annexed claims.

With reference to the accompanying drawings, wherein similar reference characters designate corresponding parts throughout the.,several views: Figure 1 is a plan of a machine embodying the features of the invention with the blank feeding cross head in advanced position. Fig. 2 is a fragmentary sectional plan of the same. Fig. 3 is a side elevation in partial section on lines 33 and 3, 3 of Fig. 1 with portions of the carrier and feeding device broken away, a blank beingindicated by broken lines, as positioned by the feeding device. Fig. 4 is a longitudinal vertical section of the feeding device taken on line 4-4 of Fig. 2, and Fig.

5 is a fragmentary elevation of the carrier viewed. from the side of the form closing track with a forming device illustrated in operation on a receptacle blank at the co nmencement of the final step in the bending process.

In the present embodimenta circular series of forming devices 1 are provided in connection with respective radially disposed lever arms 2 which are engaged'vvith fulcrums 3 on a horizontal rotatablecarrier 4 and provided with rollers 2F engagedewith an elevated cam track 5', secured to a standard 5 having a step journal 5 supporting carrier 4.

' Suitable provision is made for advancing and arresting carrier 4 so that the devices 1 will be presented successively to the blank feeding device 6 which is operated, as will be later understood, to forward a blank to a device 1 during each pause of the carrier. The mechanism for advancing carrier 4 conveniently comprises a spring pressed pallet 40 related to a continuous series of teeth 4' of carrier 4*and mounted on a vertically disposed swing arm 41 provided with a slide block 41'- which is connected with a crank 42 of a. horizontal shaft 43 journaled on standard 5 and connected by spur gearing .45 with a drive shaft 46 towhich power is applied in any convenient manner to rotate shaft 43 continuously in the direction indicated by the arrow in Fig. 3. The provision for arresting carrier 4 is in the form of a beveled segmental disk 44 secured to shaft 43 in angular relation to crank '42 for e ngagement in a successive manner, with a circular series of correspondingly beveled recesses 4" of carrier 4 to arrest the latter at the termination of each active movement of swing arm 41. Feeding device 6 comprises a cross head 30 mounted for reciprocation,

in angular relation to the forward side of a the adjacent device 1, on elevated horizontal slides 31 of a fixed support 32 and connected, by means of a link 33, with a rock arm 34 which is operated from shaft 43, to.advance head 30 during each pause of carrier 4, through the medium of an eccentric 43' and stem 34. V I

Positioned over thepath of head 30 is a container for the blanks in the form of a sector shaped frame 35 arranged with one end wall extending in a common direction with the line of feed and provided with forwardly extending bottom and end guides as 36, 36 for the blanks, as b,- which are advanced successively, frombeneath the front wall of the containerand positioned under a friction back stop 30, by a toothed engaging device 37 fixed to head 30. Each blank advanced is forwarded from stop 30' and positioned in a formingdevice 1 by gravity set push catches 38 which are pivoted on head 30in suitable arrangement forwardly of device 37 forengagement with the rear edges of the advanced blank during primary advance movement of the head from its retracted position, as indicated by broken lines in Fig. 4. a

39 designates an elevated container for adhesivematerial having a discharge spout 39' positioned over the path of feed for applying the material along one edge portion of the advanced blank as it is forwarded into the path of carrier 1.

Each device 1 includes oppositely .'disposed exterior form sections 1O, 10 hinged to an intermediate similar form section 11 fixed to an arm 2, and an interposed mandrel 12 provided with a waste adhesive receiving groove 12, and having an enlarged base 12' provided with stem extensions 13 which are pivoted to said arm for upward and downward adjustment of the mandrel with respect to section 11 to thereby open the form and subsequently efi'ect a primary bending operation on the blank, as will be later understood. This adjustment of mandrel 12 is conveniently effected, by and during relatively reverse movements of the free end of arm 2, through the medium of a roller 13' mounted on an angular extension of one stem 13 of the mandrel and engaged with a respective angular cam track 14 fixed to carrier 4. In this connection it will be ob served that track 5 is provided with an angular raised section 5 which is adapted to effect reverse angular movements of arm 2 in a direction lengthwise of the mandrel l2 and extends in the angle of device 6 to support said arm with the form section 11 inclined downwardly toward and with its outer end just beneath the plane of feed guides 36. while cam track 14 is adapted to guide roller 13 for upward and downward adjustments of mandrel 12, as form section 11 is respectively elevated and lowered, and further sustain said roller, during the blank feeding operation, with lower surface of the mandrel immediately above and substantially parallel with the feeding plane. Through the angular adjustment of form section 11 and mandrel 12, they, when the form is open, will diverge from their inner ends. Thus, their greatest relative spacing will occur at their outer or receiving ends with a view of facilitating the entrance of the blank, see Fig. 3. It will further be observed, that through the convergence of these form parts, the blank when fed into the form will be bowed or bent to concave form, with its intermediate portion bearing against the lower side portion of the mandrel. At such time the side edge portions of the blank are engaged with and overlie the form sections 10, as indicated b dotted lines in Fig. 3, to be bent by the atter against the mandrel, in a manner to be hereinafter set forth. 7

Provision is made in each device 1 for retaining the blank forwarded thereto in The form sections 10, of each device 1 are provided with arm extensions equipped with wipers or rollers 10 for cooperation with vertically movable push bars 15, mounted in slide ways 15 of form section 11 and provided with hearing rollers 15 for elevating and lowering track sections, as 16, 17, whic are positioned in the path of carrier 1 at opposite sides of the angle of track section 5*. Each slide way 15 is equipped with a releasable back stop for its bar 15 in the form of a spring pressed ball 18 mounted in a housing, as 18, for pro'ection into a suitable cavity of the bar when the latter is brought to its elevated position.

Each forming device 1 is provided with ejecting mechanism comprising oppositely disposed curved arms 20, 20 journaled on a vertical bracket 21 of base'12' of the mandrel 12 in fixed connection with a rock crank 22 and provided with angular terminations 20, 20 which, when the formin device is closed, lie in respective recesses 0? base 12 in opposing relation to the base end of the formed receptacle body. Crank 22 is connected with arm 2 of the forming device by a restraining link 23 which serves to hold the crank for angular movement to advance and retract the arms 20, 20 by and during upward and downward adjustment of the mandrel 12 with respect to the form section 11.

In operation, movement of carrier 4 to bring a forming device 1 to its receivin position is followed by an advancement 0 cross head 30, by which latter a blank is positioned in the forming device with due regard for the lapping of the gummed edge portion of the blank over the opposite edge portion thereof directly at the rear side of the mandrel groove 12. As roller 2' of the arm 2 traverses the descending end portion of the track section 5, from section 11 is elevated and mandrel 12 applied therein to effeet a primary bending operation on the blank, which is followed by the overlapping of the blank end portions by operation of form sections 10 as push bars 15 are elevated in passing track 16. During further movement of carrier 4, push bars 15 are brought to a lowered position by track 17, subsequently to which arm 2 passes the ascending portion of track section 5 and tilts by gravity with a consequent upward adjustment of mandrel 12, through the medium of roller 13' and track 14, to thereby force open form sections 10, and an outward movement ofthe ejecting arms 20, efi'ected through adjustment of crank 22 in opposition to link 23. It will be observed that crosshead 30 moves to and fro in a path extending lengthwise and obliquely of a forming device when the latter is in its open and receiving position, as clearly shown in Figs. 1 and 2. By this construction, one side edge portion of the tapered blank 1) moves in a straight line, under discharge spout 39, during its advance movement. Further, through this oblique advance or feeding movement of a blank into an open formin device, the action on the blank as it is ted both along and transversely of the mandrel 12 is to smooth it and thereby prevent any tendency toward rumpling or accidental turning over of the forward edge portion of the blank.
